To remove and install a differential pinion seal, first loosen the wheel lug nuts and raise the front or rear of the vehicle on jackstands. Remove the wheels and disconnect the driveshaft from the differential pinion flange. Rotate the pinion and record the torque required to rotate it. Mark the relationship of the pinion flange to the shaft and count the number of exposed threads on the shaft. Use a special tool or chain wrench to immobilize the flange and remove the pinion nut. Withdraw the flange and pry out the old seal. Install the new seal by lubricating the lips and tapping it evenly into position. Apply RTV sealant to the ends of the splines visible in the center of the flange and install the washer and a new pinion nut. Tighten the nut until the recorded number of threads are exposed and measure the torque required to rotate the pinion. Tighten the nut in small increments until it matches the recorded figure and exceeds it by 5 in-lbs. Reinstall all components and tighten all fasteners to their specified torque values.

The pinion flange can be immobilized using a special tool or a chain wrench.

After removing the pinion nut and companion flange, the old seal should be pried out and discarded.

Withdraw the companion flange. You may need a two or three-jaw puller engaged behind the flange to draw it out.

Use a two-jaw puller.

After removing the wheel and accessing the front axle area, you should remove the splash shield from under the front axle.

Tighten the nut carefully until the original number of threads are exposed. Measure the torque required to rotate the pinion and tighten the nut in small increments until it matches the figure recorded earlier. In order to compensate for the drag of the new oil seal, the nut should be tightened more until the rotational torque of the pinion slightly exceeds what was recorded earlier, but not by more than 5 in-lbs.

The driveshaft.

The first step is to loosen the wheel lug nuts and raise the front or rear of the vehicle on jackstands.

Before removing the pinion nut and companion flange, alignment marks should be made on the pinion shaft, nut, and flange, and the number of threads visible between the nut and shaft should be counted.

The first step is to loosen the wheel lug nuts and raise the front or rear of the vehicle on jackstands.

After tightening the pinion nut, the driveshaft should be connected, the wheels should be installed, and the vehicle should be lowered. The lug nuts should be tightened to the proper torque.
